King James Version

The
Book of Exodus

Chapter
11

And
the LORD said unto Moses, Yet will I bring one plague more upon Pharaoh, and
upon Egypt; afterwards he will let you go hence: when he shall let you go, he
shall surely thrust you out hence altogether.

And
all the firstborn in the land of Egypt shall die, from the first born of
Pharaoh that sitteth upon his throne, even unto the firstborn of the
maidservant that is behind the mill; and all the firstborn of beasts.

And all these thy servants shall come down unto me, and bow down themselves
unto me, saying, Get thee out, and all the people that follow thee: and after
that I will go out. And he went out from Pharaoh in a great anger.
